CLEANING BRUSH FOR BUTTER JARS.

Application filed August 17, 1922.

To all whomz't may concern:

Be it known that I, OLAF WEsTvIG, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Cleaning Brushes for Butter Jars; and I do hereby declare the following to be a full, clear, and exact description of the invention, suclras will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a cleaning device, and particularly to such a device constructed and arranged to clean crocks ars and similar containers. Comparatlvely small open sided crocks are now used in large numbers in certain butter factoriesand butter dispensing establishments and 1t 1s quite necessary and desirable to have these crooks thoroughly cleaned after they have been used before being re-filled.

It is an object of this invention, therefore, to provide a means for quickly and easily cleaning the inside of the crock, as well as the top edge and the exterior thereof ad acent said edge.

It is a further object of the invention to provide such a device comprising a rotating brush having brush or bristle carrying arms so disposed that the bristles or brushes will simultaneously contact the bottom, interior side, top edge and exterior of the jar or crock. 7

It is still another object of the invention to provide such arms of simple construction and a central edge to which the arms are securely connected.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the different views, and in which- Fig. 1 is a view in side elevation of the device;

Fig. 2 is a view in side elevation of the brush shown on an enlarged scale;

Fig. 3 is an end view of Fig. 2, as seen from the right hand side thereof;

Fig. 4 is a plan view on a still more enlarged scale showing the end of the brush carrying head;

Fig. 5 is a view in elevation of a portion of the brush structure, the head thereof being shown in section on a similar scale, and

Serial No. 582,397.

G is a vertical section taken on the arrows.

Referring to the drawings, the base 1 is shown which may represent the top of a table or bracket adjacent a washing tank and to which is secured the bracket 2. This bracket comprises a bearing portion atits upper end in which is journaled a shaft 3 longitudinally held in place in said bear-- ing by the collars 4 secured thereto by suit-- able set screws. The shaft 3 is connected at one side of the bearing to the motor shaft of a motor 5 shown as an electric motor suitably bolted or supported to a base carried by the member 1. The shaft 3 has at 7 its other end a multiple jaw clutch 6 of the usual type, the jaws of which are movable to clamping position by a knurled collar 7 threaded thereon, and a cleaning member designated generally as 8 is adapted to be secured in said clutch member 6.

The member 8 comprises a tapered arbor 9 adapted to fit in and be received in the jaws of the clutch 6 and said arbor extends from a substantially central head member 10. The member 10, preferably, is made of wood and a metal annular member or ring 11 is tightly fitted to the outer end thereof. The end of the head 10 is provided with transversely extending grooves 12 alining with notches or slots extending through the ring 11, said grooves being disposed substantially at right angles to each other. A plurality of brush or bristle carrying arms 13 are provided and are illustrated as made of a pair of wires twisted together and having inserted therebetween and held tightly in position thereby the bristles or brushes 1%. The arms 13 are shown as four in number and extend transversely across the end of the head member 10, being disposed in the grooves 12 and the slots in ring 11. Said arms are firmly and rigidly held in place in said head by fastening members illustrated as staples 15 which will be driven into the end of the member 10 and sunk well into the material thereof, these staples extending across and retaining the arms 13 in the slots 12. The arms 13 extend normal to the axis of the head 10 for a short distance and are then bent at substantially right angles to extend parallel to said axis for some distance, when they are again bent outwardly in a direction normal to the said axis and are finally bent reversely to extend parallel with said axis. the matter shown and described and set forth The head 10 is formed with a slot 16 opposite each of the arms 13 and a wire ring or annulus 17 is secured tightly about said head adjacent the end thereof remote from the ring 11 and members 18 are secured tosaid ring 17 and extend radially of the head to the arms 13 to which they are also rigidly secured. The arms 13, at their inner portion which extends parallel to the axis of the head 10 are thus firmly held in position and a very strong and rigid brush structure is provided.

One of the crooks operated upon is illustrated in Fig. l as B and. also indicated in dotted lines. in Fig. 2. In operation, the crock will be wet or moistened with suitable water and cleaning fluidv and will be held in theposition shown in Fig. 1 in contact with the brush 8 and the brush will be very rapidly revolved by the motor 5. It will be seen that the brushes extending across the end of the head 10' will effectively contact with the bottom of inside oi the crock B and by pressing; the crock against the brush, the bristles thereof will extend into the corners of the crock and the entire bottom will be thoroughly brushed and cleaned. It will also be noted that the inner portions of the arms 13 which are parallel to the axis of the head 10 extend along the inside wall of the crock B and will thoroughly brush and clean this portion of the crock. The portion of the brush extending outwardly from the parallel portion of the arms-13, as is clearly shown, extends across the top or end edge of the crock and will engage this portion to efficiently clean the same, while the brushes carried by the end portions of the arms l3 will be carried around in contact with the outside of the crock adjacent the top edge thereof to thoroughly cleanthe same. As the brush is rotating at high speed it will take but an instant for the brush to contact all portions of the crock to be cleaned and the cleaning operation will be very rapidly performed. The croclrs can thus bev cleaned in a small fraction of the time previously required by workmen cleaning the same with hand brushes.

From the above description it is seen that applicant has provided a very simple and highly useful and efficient cleaning device. The same can be quite easily and inexpensively made and in use will efi'ect a great saving of time and labor.

It will, of course, be understood that various. changes may be made in the form, arrangement and details of the parts without departing from the scope of applicants invention, which, generally stated, consists in in the appended claims.

What is claimed is:

l. A device for cleaning crooks, or similar containers, comprising a rotating brush having one or more bristle carrying arms, each arm being formed to extend continuously along the bottom and inner sides, and having its end curved to extend over the edge of said crock, whereby said portions of the crock will be continuously cleaned.

2. A cleaning device comprising a head, means; for rotating said head about a central axis, radial brush arms extending across the end of said head, said arms extending outward from said head, then being bent to ex tenljl. parallel to the axis thereof, the ends of said arms being bent outward from said parallel portions.

3. A cleaning device comprising a central substantially cylindrical" head having transverse grooves formed in one end thereof, means for rotating said head, radially spaced brush cleaning arms extending across said end, and disposed in said grooves, said arms extending a short distance from said head and then being bent to extend parallel to the axis of said head, and radially disposed members extending from the side of said head and connected to said arms.

a. A device of the class described, comprising, a substantially cylindrical head, means for rotating the same, radial brush carrying arms extending across one end of said head, said arms being bent at substantial'ly right angles to extend along the sides of said head, and bracing members secured to the sides of said head extending radially outwardly thereo-I" and secured to said arms.

5. A device of the class described comprising a substantially cylindrical head", means for rotating the same, an annular metal member surrounding the end of the said head, transverse intersecting grooves in said end alined with notches termed in said annular member, brush carrying arms disposed in said grooves and notches, means securing said arms to the end of the said head, said arms being bent substantially at right angles to extend along the sides of said head.

6. The structure set forth in, claim 5, an annular member embracing said head and spaced from said first mentioned annular member, radially disposed rods connectedv to said last mentioned annular member and connected to said. arms, said rods and the last mentioned annular member being disposed in slots formed in said head.

In testimony whereot I aflix my signature.
